He wanted to know how far his army would have to travel.
  In the 13thcentury, Marco Polo wrote about how the shipping businessmen flew the huge kite in the wind before the ship set sail. They predicted the voyage  in this way. If the kite went high and straight it meant a quick and successful voyage, but if it did not fly well, it was a bad omen . In the late 1500s, the kite was introduced to Europe by the Italians.
